One idea would be to draw the text into the view at the normal angle, then convert the contents of the view into an NSImage, put that into an NSImageView and rotate that instead. I'm not sure how good of a solution this is, or if there is a better solution, but I've found that manipulating images of elements rather than the elements directly is smoother.

The results are surprisingly bad (compared to how good font rendering is in general on the Mac). Most notably, the character positions "jump around" in whole pixel increments while I'm rotating the text. Usually, this is caused by hinting which tries to place vertical and horizontal lines at integer pixels. Does anyone know of a way to switch this off (temporarily) for a given context?
